12446250 ÷ 664 
We're looking to find how many times 664 goes into 12446250.

Advancing to step 1:
If we divide 1 by 664, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 664

Step 2:
12 divided by 664 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 664

On to step 3:
664 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Bring next digit (4) of the dividend behind the 124 and repeat the process: 1244 / 664

Step 4:
When dividing 1244 by 664, we get 1 with a remainder of 580.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 664 away from 1244, we end up with 580.
Grab the next digit (6) from the dividend, add it to 580, then carry on: 5806 / 664

On to step 5:
If we divide 5806 by 664, we get 8 and a remainder of 494.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 5312 from 5806 leaves us with 494.
Include the next digit (2) from the dividend after 494, then repeat: 4942 / 664

Advancing to step 6:
664 can be fit into 4942 7 times, resulting in a remainder of 294.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
The remainder is 294 after subtracting 4648 from 4942.
Bring next digit (5) of the dividend behind the 294 and repeat the process: 2945 / 664

On to step 7:
If we divide 2945 by 664, we get 4 and a remainder of 289.
Write down 4 as next digit of the result. 
Result so far: 1874.0
Deduct 2656 from 2945 and we're left with 289.
Grab the next digit (0) from the dividend, add it to 289, then carry on: 2890 / 664

Advancing to step 8:
664 can be fit into 2890 4 times, resulting in a remainder of 234.
Record the quotient 4 as the next digit in the result. 
Result so far: 18744.0
If we subtract 2656 from 2890, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Let's proceed to step 9:
664 can be fit into 2340 3 times, resulting in a remainder of 348.
Put 3 as the next digit of the answer. 
Result so far: 18744.3
Subtract 1992 from 2340 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 10:
664 goes into 3480 5 times with a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 18744.35
Deduct 3320 from 3480 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
664 goes into 1600 2 times with a remainder of 272.
Write down 2 as next digit of the result. 
Result so far: 18744.352
The remainder is 272 after subtracting 1328 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 12:
The number 664 fits into 2720 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 18744.3524
Subtract 2656 from 2720 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
664 goes into 640 0 times with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 18744.3524
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 14:
When dividing 6400 by 664, we get 9 with a remainder of 424.
The next digit of our result is 9. 
Result so far: 18744.352409
Subtracting 5976 from 6400 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 15:
664 goes into 4240 6 times with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 18744.3524096
Subtracting 3984 from 4240 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 16:
The number 664 fits into 2560 3 times, leaving a remainder of 568.
Put 3 as the next digit of the answer. 
Result so far: 18744.35240963
Subtract 1992 from 2560 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

After the division, we end up with 18744.35240963 and a remainder of 5.68e-07.
